Description
Technical field
The present invention generally relates to cordless communication network, relates more specifically to the wireless wide area network bandwidth constraint in the supervisory communications network.
Background technology
Wireless wide area network (WWAN) and equal IEEE 802.11 cordless communication networks can utilize wired or wireless access support to come to communicate by letter for their user provides, and it is professional that described wireless access is supported between user terminal and the wire/wireless territory call forwarding.Typical wired support can be digital subscriber line (DSL) or the access of other cables.Typical wireless support can for example be the access of the third generation (3G) radio honeycomb.Specifically, the access point of WWAN (AP) is made with user terminal with switch and being communicated by letter, and communication is routed to the wire/wireless territory since then.
At present, the 3G bandwidth is significantly to change, and this may throw into question to processing communication service under specific circumstances.Typical 3G bandwidth is paced up and down at present at 1Mbps, and access point (for example IEEE 802.11n is wireless) can allow each user terminal up to the bandwidth of 300Mbps.Obviously, existence is not mated between wireless access side and the WWAN.Therefore, WWAN greatly depends on access in radio (for example DSL).Yet the fault of access in radio---for example DSL fault---will stay the AP with limited wireless bandwidth for its user terminal of serving.In addition, the recovery of DSL may spend several hours to one day or the longer time.As a result, within the time of WWAN work, AP or wireless exchange board can not make all outer business of WWAN pass through via 3G.At some point, because the 3G interface is bottleneck, AP or switch queue are with saturated and lost packets.Nowadays still there is not mechanism can supply to be used for dealing with this situation.
Some solutions will be under with the situation of WWAN by traffic shaping, rate limit or use based on the packet loss of differentiated services code points and realize, the professional priority that obtains to press the order of sound, video, data, text etc. wherein.Yet, may there be some situations, for example in the shop, the owner wishes that the cash register that he sends data service has the priority higher than customer calls there.Grouping losing not conform in this case and need according to priority, because will causing the client uncontrollably critical data to be used, that remains on higher priority, and because the client can administer all available bandwidth, to cause the traffic of the limit priority in shop is lost, so that the network operation is slow.
Therefore, the new technology of needs is come the radio wide area network bandwidth constraint in the supervisory communications network.

The invention provides multiple technologies with when access in radio is lost with the limited allocated bandwidth of available wide area access to the limit priority client activity." client activity " used herein can comprise client devices and the application that operates on the client devices.In operation, the present invention keeps limit priority or key client's machine movable, and shifts or stop lower priority or non-key client activity.
Refer back to Fig. 1, illustrate the first embodiment of the present invention, this embodiment has introduced the concept of the flexible beacon of WLAN (wireless local area network).Specifically, provide the AP 100 of service the priority of client activity or equipment can be divided into movable and lower priority (non-key) activity of limit priority (key), these activities can be stored in the memory 106.For example, use the example in shop, front, provide and control under the situation of Service Access Point the storekeeper, the storekeeper can shift to its cash handler's machine data the limit priority of the audio call that exceed any client.Priority can be assigned to equipment itself or distribute to special activity on the equipment, and for example equipment can be E911 and calls out high priority is provided, and provides low priority to normal audio call.In case determine the priority of activity and/or equipment, the storekeeper can provide two or more WLAN (wireless local area network) (WLAN) for the client activity of those high priorities (key) and the client activity of those low priorities (non-key).
As shown in the figure, AP 100 supports key service WLAN 112 and one or more non-critical services WLAN 114 now.The client activity of limit priority (user A 116, user B 118), for example storekeeper's cash register or printer are movable, are assigned to crucial WLAN 112.The client activity of lower priority (user C 120, user D 122), cell phone or the laptop computer of for example accessing the consumer are assigned to non-key WLAN 114.According to the present invention, non-key WLAN allows to be operated under the flexible beacon of AP 100.Specifically, when detecting being connected of AP100 wired with it (for example DSL 108) access, the processor 104 of AP 100 128 lost efficacy but when wireless wide-area access (WWAN) 110 had available connection 130, then AP 100 is transferred to the communication 126 of the client activity among its crucial WLAN 112 3G connection 130 and goes to WWAN 110, and simultaneously AP 100 will stop at least one beacon in the WLAN 114 non-key, that allow flexible beacon, stop thus with noncritical activity (user C 120, user D 122) communicate by letter 124.The equipment of these non-key client activity that preferably, operation plan stops can at first be removed authentication by AP 100.
More preferably, if the 3G connection 130 of WWAN 110 is had the bandwidth of processing than by the more activity of use activity of crucial WLAN 112, then it may not need to stop all non-key WLAN114 or activities.Specifically, in case DSL fault, all AP provide the activity of service can be transferred to the 3G connection, if but the grouping number of losing from the formation that is in relation to 3G interface 130 exceeds a predetermined threshold, this will trigger stopping of one or more non-key WLAN 114, as previously mentioned, thus dynamically maximize the WWAN bandwidth and do not make its excess load and lose key business.
At this moment, AP has the ability (being the keystone resources monitoring) of monitoring cable port, in case and the DSL service recovery, the AP default gateway returns to access in radio, and beacon will begin beacon on again dynamically to enable non-key WLANS 114 flexibly.
Fig. 2 illustrates another embodiment of the present invention.In this case, have the 2nd an available AP200, it has the configuration identical with an AP 100 and has access in radio 230 and possible WWAN access 110.Preferably, an AP 100 and the 2nd AP 200 keep in couples and can be similarly, although these are not essential.Equally, AP 100 has at least one and allows flexible beacon, non-key WLAN 114 (crucial WLAN is not illustrated).The example that connects 128 same scene of stopping using for the DSL of an AP 100 as previously mentioned, the client devices non-key, lowest priority of at least one WLAN 114 can obtain to remove from an AP 100 grouping of authentication, and this will stop the beacon on of WLAN114.Client activity non-key, lowest priority (user C 120 is connected with user D) is forced to roam to the WLAN 212 of the 2nd AP 200 that still has DSL connection 230 subsequently.So, can proceed by the DSL connection 230,108 of the 2nd AP 200 from the communication 226 of client activity (user C 120 is connected with user D).The movable (not shown) of key client's machine can still communicate by letter 126,130 via an AP 100 with WWAN 110, such as the front for as described in Fig. 1.
Fig. 3 illustrates another embodiment of the present invention.In this case, have the 2nd an available AP200, it has with the backhaul of an AP 100 and is connected (for example mesh network), and has access in radio 230 and possible WWAN access 110.Equally, AP 100 can have at least one and allows flexible beacon, non-key WLAN 114 (crucial WLAN is not illustrated).The example that connects 128 same scene of stopping using for the DSL of an AP 100 as previously mentioned, the client devices non-key, lowest priority of at least one WLAN 114 can obtain to remove from an AP 100 grouping of authentication, and this will stop the beacon on of WLAN114.Client activity non-key, lowest priority (user C, D, E, F 120,122,320,322) is then via the access in radio 230 among backhaul bridge 300 forced roamings to the two AP 200 between the AP 100 that service is provided and the 2nd AP 200, i.e. non-key client activities are again set up with the client computer bridge and contacted.So, can proceed by the DSL connection 230,108 of the 2nd AP 200 via bridge 300 from the communication 324 of client activity.The movable (not shown) of key client's machine can still communicate by letter 130 via an AP 100 with WWAN 110, such as the front for as described in Fig. 1.
Selectively, the configuration of Fig. 3 can be used for balancing dynamic load, and each access point of taking this under the mesh mode can make its non-key client activity load balance between base station bridge and client computer bridge.Specifically; when DSL is connected to when shutting down on the bridge of base station; AP 100 can remove authentication to half client activity on the non-key WLAN 314 (user C 120 and user D 122); and force to make these client activity roam to the client computer bridge; and second half non-key (and/or crucial) client activity (user E 320 and user F 322) can be used 3G interface 130,110; obtain thus business less on the 3G interface and load balance, because the 2nd AP 299 has than AP 100 business still less that service is provided.
Fig. 4 illustrates the flow chart according to the method for the wireless wide area network bandwidth constraint in the supervisory communications network of the present invention.
The method starts from providing the access point of service to determine client activity and/or priority facility.It is definite that everyone of anticipation access point (AP) will control this priority.Although determine that the priority of client devices is the easiest, however because client activity may be in relation to particular device, therefore will be appreciated that client devices can carry out different movable and only determine that the priority of the activity on the equipment is useful.Preferably, but the client devices Priority-based is partitioned into different WLAN (wireless local area network) (WLAN), for example critical activity is grouped among the WLAN and with noncritical activity and divides into groups into one or more other WLAN.So, priority assignment can be given a WLAN, and wherein all activity.Selectively, the priority of determining client activity can be dependent on the intraday time and dynamically changes.For example, from the morning 9:00 to 5:00 in afternoon, cash register will have high priority, but from afternoon 5:00 to 10:00 in afternoon, back-up system will have higher priority.According to the present invention, allow non-key WLAN to make its beacon stop (being flexible beacon), as hereinafter will describing in detail.
When wireless wide-area access activity, by detecting stopping using of 402 wired territory accesses, AP starts working.In other words, the fault during for example DSL connects will cause the fault to movable WWAN territory to shift.This fault also may cause in case of necessity stopping non-key WLAN beacon on.
If AP detects wired domain browsing fault, then AP is used for the available bandwidth of WWAN territory access the client activity of 404 limit priorities.Preferably, the limit priority activity is grouped together in the equipment of the upper work of crucial WLAN.The lowest priority activity can be stopped or shift.More preferably, if connection has the bandwidth of processing than by the more activity of use activity of crucial WLAN to WWAN, then it may not need to stop all non-key activities.Specifically, when the DSL fault occured, all activities can be transferred to WWAN and connect, if but exceed a predetermined threshold from the packet count that the formation that is in relation to the WWAN interface is lost, then will trigger stopping of WLAN.
A kind of technology that stops client activity is that authentication 406 is removed in the client devices/activity on the non-key WLAN.Can so do for each client devices on the specific non-key WLAN or armamentarium.Can be subsequently by stopping to this WLAN beacon on 408 specific WLAN being stopped, because WLAN can respond to flexible beacon.Critical activity can continue to communicate by letter at WWAN.
A kind of technology that stops client activity also can be removed authentication 406 to the client devices/activity on the non-key WLAN.Can so do for each client devices on the specific non-key WLAN or armamentarium.Specific WLAN can stop by this WLAN is stopped beacon on 408, this force 410 make the lowest priority client activity via the WLAN roaming in the second wireless network to other available access in radios.Critical activity can continue to communicate by letter at WWAN.
The another technology that stops client activity also can be removed authentication 406 to the client devices/activity on the non-key WLAN.Can so do for each client devices on the specific non-key WLAN or armamentarium.Specific WLAN can stop by this WLAN is stopped beacon on 408, and this forces 412 to make the lowest priority client activity roam to other available access in radios via the backhaul bridge between the access point that service is provided and the second access point.Critical activity can continue to communicate by letter at WWAN.
Selectively, can be used for balancing dynamic load via the pressure 412 of backhaul bridge, take this each access point under the mesh mode and can make its non-key client activity between base station bridge and client computer bridge load balance that becomes.Specifically, when DSL is connected to when falling on the bridge of base station, AP can remove authentication 406 to the part on the non-key WLAN (for example half) client activity, and force to make these client activity roam to the client computer bridge, and the non-key client activity of another part (for example half) can use WWAN to connect.
